Industrial Process & Productivity Improvement:Duck Farm Waste Treatment Plant(ST7973-1)

H.F. Corwin & Son, Inc.

Background

H.F. Corwin and Son, Inc. (H.F. Corwin) operates a 140 acre duck farm in Aqueboque (Suffolk County), New York. The facility has operated continuously since 1908 and is one of four duck farms remaining on Long Island. The Suffolk County Board of Health requested that H.F. Corwin pursue methods to reduce the nitrogen concentration in its treated wastewater effluent. The effluent was initially conveyed directly into large, open, earthen aeration lagoons, with subsequent discharge to groundwater via constructed sandbeds (near the Peconic Estuary system).

Project Description

With co-funding from NYSERDA, H.F. Corwin constructed an innovative waste treatment system to treat the farm’s process wastewater and barn wastewater. The system features both aerobic and anaerobic processes and is “hard bottomed”. Barn wastewater, with high solids content, is sent through a complete mix anaerobic system to maximize BOD removal and convert TKN to ammonia. Following the anaerobic treatment step, process wastewater is combined with the barn wastewater and sent through an aerobic treatment system. Biogas generated from the anaerobic system is used to power the engines that produce compressed air for the aerobic process.

Benefits

Minimized waste production, reduced electric energy consumption, and reduced nitrogen discharge to Peconic Bay.

Project Results

The installed project eliminates 300 HP of blower capacity. The effluent nitrogen concentration is reduced by approximately 375,000 pounds of nitrogen. The treatment system provides for reuse of approximately 8 million gallons of water annually, as well as $146,000 of avoided sludge disposal costs and a 10% increase in production capacity.
